I’d already tried it and hadn’t been convinced.
I really like the Vivaldi browser for its speed, and it seemed to work well with a few hundred RSS feeds. But reading some 2,000 RSS feeds is a nightmare – not only is the interface ill-suited, but it also completely saturates itself.
I’ve just given RSS Guard another go and I must admit I don’t understand my initial judgement: it’s attractive, powerful and fast. Brilliant! A big thank you for helping me rediscover it! 🙏️👍️
